Abstract
In this study, the effect of using conventional crushing and high-pressure grinding rolls
(HPGR) in combination with dry or wet milling was investigated using a base-metal sulphide (BMS)
sphalerite and a platinum group mineral (PGM) ore to determine how these processes affect the flotation
performance. In sphalerite, irrespective of the crushing procedure (HPGR or conventional), dry milling
resulted in the highest grades and recoveries of zinc, whereas in PGMs, similar treatment produced the
poorest results. The results were investigated further by the effect of factors such as percentage liberation
and particle size on the flotation results.
